The man accused in the killing of a beloved Queens teenager will spend decades behind bars after being sentenced on Wednesday.

Sean Brown was sentenced to 30 years in prison: 25 years for manslaughter in the shooting death of 14-year-old Aamir Griffin, a Cardozo High School basketball standout, in 2019, and and additional five years for an unrelated gun charge.

Brown, who was 18-year-old at the time of the shooting death, fired three times, according to Queens District Attorney Melinda Katz, from a .38 caliber gun, with one of the bullets striking Griffin in the torso. The reputed gang member fired off several shots at the basketball court, mistaking Griffin for a rival gang member whom Brown believed had stolen his phone.

Instead, Griffin was shot and killed as he was practicing on the courts at the Baisley Park Houses.

"People make mistakes and I know this is one mistake you wish you never made," Shaneqwa Griffin, Aamir's mother, said to Brown at the sentencing. "You took my son from me. I haven’t sleep in four or five years."

Griffin’s grandmother also spoke, describing Aamir as a compassionate teen with dreams of making it to the NBA.

"May God have mercy on your soul for the pain and suffering you have inflicted upon us," said Quaintana Griffin.

During Wednesday's sentencing, Brown tried to withdraw his plea deal again, which Judge Kenneth Holder called a “dilatory tactic.” Brown said he was trying to buy time to get a new lawyer.

On March 14, he participated in jury selection, was going to go to trial and decided to accept the plea deal then. Earlier this year in January, Brown rejected a plea deal and asked for a trial.

Ultimately, on Wednesday Holder denied the plea deal withdrawal and moved forward with sentencing. The judge also denounced the rise in youth offenders responsible for shootings. He said Brown is the result of the culture of gang violence and that’s he going to have a lot of time to think about his actions.

"The area of South Jamaica seems to be a shooting gallery," Holder said.

Surveillance video of the tragic Oct. 26 shooting shows Brown fleeing the scene in the moments after the shooting, even admitting he hit his rival in the head.

"But the person he thought he killed was not the teenager whose last breath was on this basketball court," Katz said.

Brown was subsequently arrested in California, and was later returned to New York City to face charges.

The South Jamaica community has worked tirelessly to keep Griffin's spirit alive in the years since his death, even completing a renovation of the basketball court where he died with photos of the teen.

After the sentencing, Aamir's mother was asked if she felt some sense of closure.

"Little bit. Not much. It doesn’t change the situation. It doesn’t change the fact that my son is no longer here," she said.
